摘　　要：超高频局部放电检测方法具有优越的抗干扰性能与较高的检测灵敏度,因此采用此种方式实现GIS局部放电的测量与分析,并设计了一种基于PCI-9812数据采集卡的局部放电检测装置,利用该检测装置对放电信号进行实时测量,对其软硬件设计进行了说明。为检验其效果构建了由实际产品部件组成的110kVGIS实验模型,设计了一种典型的局部放电模型,结果表明该装置能完成GIS局部放电的测量与分析,为基于超高频法的GIS局部放电在线监测更深入研究打下了基础。Ultra high frequency partial discharge detection method has advantages in interference immunity and detection sensitivity,so it is used in this article for the measurement and analysis of GIS partial discharge.This article designs the partial discharge detection device based on PCI-9812 data acquisition card and its hardware and software design are also described.In order to test its effect,this article builds the 110kV GIS experimental model from actual product components and a typical partial discharge model.It is shown that this device can complete the measurement and analysis of partial discharge,so this lays a foundation for further study of partial discharge monitoring based on ultra-high frequency method.
